Improving Armor, Helmets and Diagnosis

Materials scientists at NYU-Poly and NYU found that foam used in helmets and body armor can cause as much injury as hard material when under high loads such as sharp impacts or shock waves from explosives.  In a counter-intuitive finding, scientists at New York University (NYU) and Polytechnic Institute of New York University (NYU-Poly) report that the foam used in helmets and other body armor indeed absorbs damage when compressed slowly but can cause as much injury as a hard object.
